Japanese scientists, who last year received from Yakutia fragments of mammoth carcasses, reported today that this material is practically impossible to use for cloning a prehistoric beast. They intend to appeal to the Russian colleagues to send new samples.
"We want to continue to recreate the mammoth project, and intend to appeal to the Russian scientist with a request to send us additional samples of muscle tissue, — said the head of the research group of the Faculty of Bioengineering Kinki University professor Akira Iritani. — The molecules of DNA in the nucleus of our existing cells are damaged too much and not are suitable for cloning. "
Last summer, he worked hard to find a survivor of the genetic material in the tissue of a mammoth, who died about 30 million years ago. The remains were found during excavations of the Arctic Circle in the Yakut tundra in 2002. In July last five samples were taken to Japan. Professor Iritani said at the time that the mammoth could be cloned in three years, but the project stalled at the first stage.
The relative success of laborious microbiological analysis was only a confirmation of the fact that "the remains of the mammoth really belong." In the 1990s, the Japanese had already been a fiasco in an attempt to clone extinct animals found in Yakutia from pieces of skin. It turned out, in particular, that the skin is not only deprived of the full genetic material, but did not belong to the mammoth and the woolly rhinoceros. ITAR-TASS.
